Your email provider rejected the message

Short answer

The company's own email provider refused the send — WinkScope never silently swallows that. The provider API key saved in WinkScope is invalid, or the from-address has not been verified with that provider.

What it means

The company's own email provider refused the send — WinkScope never silently swallows that.

Why it happens

The provider API key saved in WinkScope is invalid, or the from-address has not been verified with that provider.

How to fix it

1. Open Settings and check the connected email provider's API key.
2. Confirm the from-address is verified inside the provider's own dashboard.
3. Check the sender name saved for the custom provider before sending.
4. Or choose Send via WinkScope in the send dialog — that route always works and does not use the company's provider.

Other ways this is described

• api key not working
• sending failed custom email
• resend key invalid
• sendgrid key invalid
• from address not verified
